We consider a vertically related market characterized by downstream imperfect competition and by the monopolistic provision of an essential facility-based input, whose price is set by a social-welfare maximizing regulator. Our model shows that the regulatory knowledge about the cost for...

We anlyze the stochastic control approach to the dynamic maximization of the robust utility of consumption and … investment. The robust utility functionals are defined in terms of logarithmic utility and a dynamically consisten convex risk … factor process: Our main results give conditions on the minimal penalty function of the robust utility functional under which …

As a result, it turns out that the possibility of a particular generalization depends on specific … properties of the utility functional under consideration. -- monetary utility functionals ; optimal stopping ; duality ; policy …

The background for the general mathematical link between utility and information theory investigated in this paper is a … represented by an enlargement of the other agents' filtration. The expected logarithmic utility increment, i.e. the difference of … the insider's and the less informed trader's expected logarithmic utility is described in terms of the information drift …

A new test for constant correlation is proposed. Based on the bivariate Student-t distribution, this test is derived as Lagrange multiplier (LM) test. Whereas most of the traditional tests (e.g. Jennrich, 1970, Tang, 1995 and Goetzmann, Li & Rouwenhorst, 2005) specify the unknown correlations as...

Generally, Democrats do not increase military spending, and Republicans do not raise welfare payments. Mostly, ruling politicians stick to the manifesto of their party. The current paper provides a theoretical explanation for this phenomenon that does not assume politicians or voters to be...
